In contrast, leiomyosarcoma (LMS) of the uterus is a rare entity with an annual incidence quoted between 0.014 0.28% [1, 11, 12].
In contrast, leiomyosarcoma of the uterus is a rare entity with an annual incidence quoted at 0.64/100,000 women [13].
Recent estimates of GIST annual incidence quoted in the United Kingdom (UK) range from 1.32 1.50 per 100,000 population, although none appear population-based [ 3, 4], equivalent to approximately 800 900 new cases each year [ 4].
The incidence figure quoted above excludes bicuspid aortic valve, which is present in 1 2% of live births, but is usually not detected until much later in life, if at all.
Incidence rates quoted were calculated per 100,000 population by using the relevant 2003 annual population estimate for each local authority area, purchased from the UK Office for National Statistics.
Virtually all children are infected at least once within the first 5 years of life, with the peak incidence widely quoted as occurring between 6 and 24 months of age (5, 7, 11, 13, 14, 16, 20-23).
There are five studies that generated population incidence rates, quoting a range from 0.5 to 1.5 cases/1000 persons.
Pin track infection is almost inevitable during the long-term use of external fixators with the quoted incidence ranging from 11.3 to 100%% [3, 4, 5, 6, 7, 8, 9, 10, 11].
Most previous epidemiological studies of DD that have quoted incidence rates were in fact referring to prevalence rate [ 15].
Despite the often quoted 'typical incidence' figures of 85% CIN and 15% MSI in CRC, the incidence of CIN varied between 35 70% in these studies, while MSI varied from 5 23% and tumours showing neither CIN nor MSI were common (19 52%).
This is not unexpected as its incidence rate is often quoted to be low and is rarely quantified [9, 12, 13].
